optimization/10196: [3.3/3.4 regression] Compile time regression with inlining

[Richard Guenther]

The problem seems to come from changes in exception handling between
3.2 and 3.3. If I specify -fno-exceptions the compile time regression
between 3.2 and 3.3 reduces to 8.6s vs. 10s total time, without
-fno-exceptions it is 10s vs. 146s (otherwise just -O2). The same
testcase compiled with -fno-exceptions (libstdc++ stuff differs and
is incompatible) can be fetched at

I'm now trying to collect profiles for both cases
